epac1

ESI-09 is a new-typel noncyclic nucleotide EPAC antagonist.The IC50 values of ESI-09 for EPAC1 and EPAC2 is 3.2 and 1.4 μM, respectively.

HJC0197 selectively blocks cAMP-induced Epac activation. HJC0197 is an effective exchange protein. Which straightly activated by cAMP (Epac) antagonist (IC50=5.9 μM for Epac2).

HJC0350 is an effective and specific EPAC2 inhibitor (IC50: 0.3 μM), and no inhibition of Epac1.

EPAC 5376753 is an allosteric inhibitor of EPAC1 with an IC50 of 4 µM in Swiss 3T3 cells.

(R)-CE3F4 is a selective inhibitor of exchange protein directly activated by cAMP isoform 1 (Epac1)(IC50 of 4.2 μM),

8-CPT-2Me-cAMP sodium is a sodium salt compound that selectively activates exchange proteins activated by cAMP (Epac), which are cAMP-sensitive guanine nucleotide exchange factors (GEFs) responsible for activating small GTPases Rap1 and Rap2. It specifically activates Epac1 with an EC50 value of 2.2 μM, while showing no activation of PKA with an EC50 value greater than 10 μM [1]. Additionally, 8-CPT-2Me-cAMP sodium stimulates the Epac-mediated release of calcium ions (Ca2+) in vitro in pancreatic β-cells [2].

ESI-08 is an effective antagonist of EPAC2 with an IC50 of 8.4 μM. ESI-08 selectively blocks cAMP-induced EPAC activation but not cAMP-mediated PKA activation.

I942 is a novel, selective ACyclic nucleotide (NCN) EPAC1 agonist that activates exchange proteins to regulate inflammatory gene expression in human umbilical blood tubes and inhibit pro-inflammatory cytokine signaling associated with cardiovascular disease.

AM-001 is a non-competitive inhibitor of Epac1, preventing the activation of its downstream effector Rap1 in cultured cells. This compound is utilized in research related to cardiac diseases.

CE3F4 is a selective antagonist of exchange protein directly activated by cAMP (Epac1; IC50s of 10.7 μM and 66 μM for Epac1 and Epac2(B), respectively).
